Pokémon dark souls

One day me and my group were talking about the new Pokémon games and an idea came up of a pokemon dark souls game. The concept was that the game would basically be like the dark souls format but the main characters would be Pokémon and bosses would be Pokémon. You would start off the game by picking a starter to play as and then you would level up like in dark souls. Kind of like Pokémon dungeon but you would have armor and items that would help you throughout the game and the bosses would be way harder with unique fighting styles and powerful move sets. and the graphics and art style would be dark souls base too. We were basically asking for a more mature/challenging Pokémon dungeon lol
